Neil Simon's 1980 comedy starring Chevy Chase, Goldie Hawn, Robert Guillame, and Charles Grodin is a very, very funny movie, from start to finish. Nick Gardenia (Chase), is a divorced novelist who is living a simple, quiet life. He just wants to work on his book. But things start to go bad right away, as he is visited by two low-life crooks who want to use him as a decoy of sorts. Under the threat of death, or at least, serious bodily harm, he is forced to rob a bank, and as they all make their getaway, he is thrown from the car and left by the side of the road to fend for himself, as he is the one caught on the bank's surveillence camera. He is now a fugitive with all of the state's police force searching for him.
Desperate, he shows up at the home of his ex-wife, Glenda Parks (Hawn), a defense attorney, and his only hope. She is a very kind-hearted woman with a beautiful soul and a soft spot for the downtrodden, maybe she'll help? The problem is, her current husband, Ira Parks (Charles Grodin), is about to be appointed Attorney General, and if he finds Nick hiding in his house, he'll turn him in to the police, probably after a quick roughing up. And if anyone finds him there, Ira could easily lose all chances at his beloved Attorney General position, because his wife is harboring a fugitive. So Glenda has to hide Nick from Ira and everyone else as she tries to convince him to turn himself in, all the while they are about to throw an elegant dinner party celebrating Ira's good fortune, and Glenda has to play dumb, as if all is well.
As the plot unfolds, we see that Glenda still has some strong feelings for Nick, and she is very conflicted; ethically, she must defend Nick in court, but personally she must turn off her long dormant feelings for him. And Ira can't find out she has been harboring him. And the situation becomes more and more complex as a second dinner party approaches; The governor himself is invited this time, and Nick, through a series of strange twists, winds up helping to serve the food and drinks at this particular dinner party.
This film has large doses of physical and verbal humor throughout, chiefly Chase's pratfalls, per his days from "Saturday Night Live" (he was an original cast member in 1975), and Hawn's character's gradual breakdown from the stress of hiding her ex-husband from her current husband; Goldie Hawn is a very good comic actress, and in this particular story, she's brilliant.
It's an excellent screenplay, well-executed direction, and brilliant comedy throughout.
One caviat, if you expect a lot of extra features, or any features, for that matter, you'll be disappointed; there aren't any. But this is such a good movie, that shouldn't matter.
I have watched this movie many times since 1980, and laugh out loud every time.
